Thanks, I was not aware of its existence. I will definitely subscribe
to this list.
Greetings, Richard

I am developing a prototype to save SAR data at various levels and
processing
stages in HDF5 format.
In order to properly describe this data (e.g. the side looking
geometry or
orbit information in form of state vectors), I would need to generate a
larger number of attributes that would benefit from a structure in
groups.
The majority of the attributes would apply to all data sets.
Sometimes, you
will have several bands in a data set with a very limited number of
attributes specific to the band (e.g. its polarization). Is there a
standard
way of going about saving this type of metadata structure in HDF5?
Another somewhat related question is how to handle map projection
information for geocoded data. Any best practice for that?
Please, take a look at the CF metadata conventions:
http://cf-pcmdi.llnl.gov/
It assumes that you use netCDF, but using netCDF-4 you can write well
structured HDF5 files, or you can follow the conventions using standard
HDF5 functions.
I have participated in a small project called ADAGUC where we tried to
address also the meta data for remote sensing datasets:
http://adaguc.knmi.nl/
Good luck, Richard
The cf conventions are being actively developed at the moment for satellite
data. Take a look here:
